Inevitable wardrobe malfunction? Adrienne Maloof suffered a nip slip on Saturday, June 1, when she stepped out in an ultra-revealing ensemble that essentially guaranteed a fashion mishap.

The former Real Housewives of Beverly Hills star, 51, styled a sheer, cleavage-baring black jumpsuit for a date night with Sean Stewart, 32, at Chateau Marmont in West Hollywood. Maloof's jumpsuit accidentally exposed her nipple when the top pulled to one side.

Maloof began dating rocker Rod Stewart's son in January 2013, shortly after finalizing her divorce from Dr. Paul Nassif. Maloof and Stewart split back in March, but have maintained a friendly relationship since then.

"They've decided to distance themselves and become friends. Nothing bad happened," a source close to Maloof told Us Weekly. "They're still going to hang out as friends, they enjoy each other's company."

The single mother of three has a little more time on her hands now that she's no longer appearing on The Real Housewives of Beverly Hills. After failing to attend the season 3 reunion special in March, Maloof announced she had decided to leave the Bravo reality show. Costar Lisa Vanderpump, however, told Us that she "got the hoof."

"The reunion is where you go and everything comes to fruition and you hash it out. And viewers want that the same way they want us to blog. . . So yeah, she got the hoof!" Vanderpump said. "She says she walked away, but she didn't. She got the big Maloof hoof! And you can quote me on that!"
